Proximity fuze

Proximity fuze MK53 removed from shell, circa 1950s

A proximity fuze (also VT fuze[1][2][3] or "variable time fuze") is a fuze that detonates an explosive device automatically when it approaches within a certain distance of its target. Proximity fuzes are designed for elusive military targets such as aircraft and missiles, as well as ships at sea and ground forces. This sophisticated trigger mechanism may increase lethality by 5 to 10 times compared to the common contact fuze or timed fuze.[4][5]
